The following lists the names, descriptions, and values of the special request parameters that the CreateQueue action uses:    DelaySeconds – The length of time, in seconds, for which the delivery of all messages in the queue is delayed. Valid values: An integer from 0 to 900 seconds (15 minutes). Default: 0.     MaximumMessageSize – The limit of how many bytes a message can contain before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes (1 KiB) to 262,144 bytes (256 KiB). Default: 262,144 (256 KiB).     MessageRetentionPeriod – The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer from 60 seconds (1 minute) to 1,209,600 seconds (14 days). Default: 345,600 (4 days).     Policy – The queue's policy. A valid AWS policy. For more information about policy structure, see Overview of AWS IAM Policies in the Amazon IAM User Guide.     ReceiveMessageWaitTimeSeconds – The length of time, in seconds, for which a  ReceiveMessage  action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.     RedrivePolicy – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. For more information about the redrive policy and dead-letter queues, see Using Amazon SQS Dead-Letter Queues in the Amazon Simple Queue Service Developer Guide.    deadLetterTargetArn – The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of maxReceiveCount is exceeded.    maxReceiveCount – The number of times a message is delivered to the source queue before being moved to the dead-letter queue. When the ReceiveCount for a message exceeds the maxReceiveCount for a queue, Amazon SQS moves the message to the dead-letter-queue.    The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.     VisibilityTimeout – The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. For more information about the visibility timeout, see Visibility Timeout in the Amazon Simple Queue Service Developer Guide.   The following attributes apply only to server-side-encryption:    KmsMasterKeyId – The ID of an AWS-managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms. While the alias of the AWS-managed CMK for Amazon SQS is always alias/aws/sqs, the alias of a custom CMK can, for example, be alias/MyAlias . For more examples, see KeyId in the AWS Key Management Service API Reference.     KmsDataKeyReusePeriodSeconds – The length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt messages before calling AWS KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period provides better security but results in more calls to KMS which might incur charges after Free Tier. For more information, see How Does the Data Key Reuse Period Work?.    The following attributes apply only to FIFO (first-in-first-out) queues:    FifoQueue – Designates a queue as FIFO. Valid values are true and false. If you don't specify the FifoQueue attribute, Amazon SQS creates a standard queue. You can provide this attribute only during queue creation. You can't change it for an existing queue. When you set this attribute, you must also provide the MessageGroupId for your messages explicitly. For more information, see FIFO Queue Logic in the Amazon Simple Queue Service Developer Guide.    ContentBasedDeduplication – Enables content-based deduplication. Valid values are true and false. For more information, see Exactly-Once Processing in the Amazon Simple Queue Service Developer Guide. Note the following:    Every message must have a unique MessageDeduplicationId.   You may provide a MessageDeduplicationId explicitly.   If you aren't able to provide a MessageDeduplicationId and you enable ContentBasedDeduplication for your queue, Amazon SQS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).    If you don't provide a MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication set, the action fails with an error.   If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.     When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.   If you send one message with ContentBasedDeduplication enabled and then another message with a MessageDeduplicationId that is the same as the one generated for the first MessageDeduplicationId, the two messages are treated as duplicates and only one copy of the message is delivered.       Preview: High throughput for FIFO queues   High throughput for Amazon SQS FIFO queues is in preview release and is subject to change. This feature provides a high number of transactions per second (TPS) for messages in FIFO queues. For information on throughput quotas, see Quotas related to messages in the Amazon Simple Queue Service Developer Guide. This preview includes two new attributes:    DeduplicationScope – Specifies whether message deduplication occurs at the message group or queue level. Valid values are messageGroup and queue.    FifoThroughputLimit – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are perQueue and perMessageGroupId. The perMessageGroupId value is allowed only when the value for DeduplicationScope is messageGroup.   To enable high throughput for FIFO queues, do the following:   Set DeduplicationScope to messageGroup.   Set FifoThroughputLimit to perMessageGroupId.   If you set these attributes to anything other than the values shown for enabling high throughput, standard throughput is in effect and deduplication occurs as specified. This preview is available in the following AWS Regions:   US East (Ohio); us-east-2   US East (N. Virginia); us-east-1   US West (Oregon); us-west-2   Europe (Ireland); eu-west-1   For more information about high throughput for FIFO queues, see Preview: High throughput for FIFO queues in the Amazon Simple Queue Service Developer Guide.

Amazon SQS interprets tags as character strings.   Tags are case-sensitive.   A new tag with a key identical to that of an existing tag overwrites the existing tag.   For a full list of tag restrictions, see Limits Related to Queues in the Amazon Simple Queue Service Developer Guide.  To be able to tag a queue on creation, you must have the sqs:CreateQueue and sqs:TagQueue permissions. Cross-account permissions don't apply to this action.

FifoThroughputLimit – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are perQueue and perMessageGroupId. The perMessageGroupId value is allowed only when the value for DeduplicationScope is messageGroup.   To enable high throughput for FIFO queues, do the following:   Set DeduplicationScope to messageGroup.   Set FifoThroughputLimit to perMessageGroupId.   If you set these attributes to anything other than the values shown for enabling high throughput, standard throughput is in effect and deduplication occurs as specified. This preview is available in the following AWS Regions:   US East (Ohio); us-east-2   US East (N. Virginia); us-east-1   US West (Oregon); us-west-2   Europe (Ireland); eu-west-1   For more information about high throughput for FIFO queues, see Preview: High throughput for FIFO queues in the Amazon Simple Queue Service Developer Guide.

If a networking issue occurs after a ReceiveMessage action, and instead of a response you receive a generic error, it is possible to retry the same action with an identical ReceiveRequestAttemptId to retrieve the same set of messages, even if their visibility timeout has not yet expired.   You can use ReceiveRequestAttemptId only for 5 minutes after a ReceiveMessage action.   When you set FifoQueue, a caller of the ReceiveMessage action can provide a ReceiveRequestAttemptId explicitly.   If a caller of the ReceiveMessage action doesn't provide a ReceiveRequestAttemptId, Amazon SQS generates a ReceiveRequestAttemptId.   It is possible to retry the ReceiveMessage action with the same ReceiveRequestAttemptId if none of the messages have been modified (deleted or had their visibility changes).   During a visibility timeout, subsequent calls with the same ReceiveRequestAttemptId return the same messages and receipt handles. If a retry occurs within the deduplication interval, it resets the visibility timeout. For more information, see Visibility Timeout in the Amazon Simple Queue Service Developer Guide.  If a caller of the ReceiveMessage action still processes messages when the visibility timeout expires and messages become visible, another worker consuming from the same queue can receive the same messages and therefore process duplicates. Also, if a consumer whose message processing time is longer than the visibility timeout tries to delete the processed messages, the action fails with an error. To mitigate this effect, ensure that your application observes a safe threshold before the visibility timeout expires and extend the visibility timeout as necessary.    While messages with a particular MessageGroupId are invisible, no more messages belonging to the same MessageGroupId are returned until the visibility timeout expires. You can still receive messages with another MessageGroupId as long as it is also visible.   If a caller of ReceiveMessage can't track the ReceiveRequestAttemptId, no retries work until the original visibility timeout expires. As a result, delays might occur but the messages in the queue remain in a strict order.   The maximum length of ReceiveRequestAttemptId is 128 characters. ReceiveRequestAttemptId can contain alphanumeric characters (a-z, A-Z, 0-9) and punctuation (!"#$%&amp;'()*+,-./:;&lt;=&gt;?@[\]^_`{|}~). For best practices of using ReceiveRequestAttemptId, see Using the ReceiveRequestAttemptId Request Parameter in the Amazon Simple Queue Service Developer Guide.

Valid values: An integer from 1,024 bytes (1 KiB) up to 262,144 bytes (256 KiB). Default: 262,144 (256 KiB).     MessageRetentionPeriod – The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer representing seconds, from 60 (1 minute) to 1,209,600 (14 days). Default: 345,600 (4 days).     Policy – The queue's policy. A valid AWS policy. For more information about policy structure, see Overview of AWS IAM Policies in the Amazon IAM User Guide.     ReceiveMessageWaitTimeSeconds – The length of time, in seconds, for which a  ReceiveMessage  action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.     RedrivePolicy – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. For more information about the redrive policy and dead-letter queues, see Using Amazon SQS Dead-Letter Queues in the Amazon Simple Queue Service Developer Guide.    deadLetterTargetArn – The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of maxReceiveCount is exceeded.    maxReceiveCount – The number of times a message is delivered to the source queue before being moved to the dead-letter queue. When the ReceiveCount for a message exceeds the maxReceiveCount for a queue, Amazon SQS moves the message to the dead-letter-queue.    The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.     VisibilityTimeout – The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. For more information about the visibility timeout, see Visibility Timeout in the Amazon Simple Queue Service Developer Guide.   The following attributes apply only to server-side-encryption:    KmsMasterKeyId – The ID of an AWS-managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms. While the alias of the AWS-managed CMK for Amazon SQS is always alias/aws/sqs, the alias of a custom CMK can, for example, be alias/MyAlias . For more examples, see KeyId in the AWS Key Management Service API Reference.     KmsDataKeyReusePeriodSeconds – The length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt messages before calling AWS KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period provides better security but results in more calls to KMS which might incur charges after Free Tier. For more information, see How Does the Data Key Reuse Period Work?.    The following attribute applies only to FIFO (first-in-first-out) queues:    ContentBasedDeduplication – Enables content-based deduplication. For more information, see Exactly-Once Processing in the Amazon Simple Queue Service Developer Guide. Note the following:    Every message must have a unique MessageDeduplicationId.   You may provide a MessageDeduplicationId explicitly.   If you aren't able to provide a MessageDeduplicationId and you enable ContentBasedDeduplication for your queue, Amazon SQS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).    If you don't provide a MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication set, the action fails with an error.   If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.     When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.   If you send one message with ContentBasedDeduplication enabled and then another message with a MessageDeduplicationId that is the same as the one generated for the first MessageDeduplicationId, the two messages are treated as duplicates and only one copy of the message is delivered.       Preview: High throughput for FIFO queues   High throughput for Amazon SQS FIFO queues is in preview release and is subject to change. This feature provides a high number of transactions per second (TPS) for messages in FIFO queues. For information on throughput quotas, see Quotas related to messages in the Amazon Simple Queue Service Developer Guide. This preview includes two new attributes:    DeduplicationScope – Specifies whether message deduplication occurs at the message group or queue level. Valid values are messageGroup and queue.    FifoThroughputLimit – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are perQueue and perMessageGroupId. The perMessageGroupId value is allowed only when the value for DeduplicationScope is messageGroup.   To enable high throughput for FIFO queues, do the following:   Set DeduplicationScope to messageGroup.   Set FifoThroughputLimit to perMessageGroupId.   If you set these attributes to anything other than the values shown for enabling high throughput, standard throughput is in effect and deduplication occurs as specified. This preview is available in the following AWS Regions:   US East (Ohio); us-east-2   US East (N. Virginia); us-east-1   US West (Oregon); us-west-2   Europe (Ireland); eu-west-1   For more information about high throughput for FIFO queues, see Preview: High throughput for FIFO queues in the Amazon Simple Queue Service Developer Guide.
